Re: [R] how to analyze the following data?--anxious for the result

Asserting `y isn't noramal' only eliminates one possibility. Is it binary, a count, long-tailed, short-tailed, ...?

This is really a statistical consulting problem (and apparently about SAS): see the R posting guide for where to seek advice on such problems. As the guide says, had we had sufficient information we might have been able to help, but as you need to ask again, please do so in a more appropriate place.
